新疆北部为害胡杨的三种木虱形态识别及为害特征研究初探

【目的】查明为害新疆胡杨三种木虱的形态及为害特征,为研究其生物学特性和综合防控奠定基础。【方法】在胡杨林区定期定点观察和普查相结合,对采集的昆虫标本进行显微镜观察、鉴定。【结果】经过实地调查研究,初步确定了为害胡杨的木虱有三种,即蔡氏胡杨个木虱(Egeirotrioza ceardi)、纤细真胡杨个木虱(Evegeirotrioza gracilis)和无斑滑头木虱(Homalocephala uncolor)。【结论】三种胡杨的木虱,在胡杨树上混合发生。在同一棵胡杨树上可见三种木虱及为害状,只是为害时间有所差异。蔡氏胡杨个木虱发生最早,其次为无斑滑头木虱和纤细真胡杨个木虱,无斑滑头木虱的若虫为害时间早于纤细真胡杨个木虱。

Morphological Identification and Damage Characteristics of Three Populus Euphratica Psyllid in Northern Xinjiang

Objective]The research aimed to detect morphological identification and damage characteristics of three Populus euphratica psyllid and lay the foundation for the next research of the biological and integrated control technology.Method]Regular observation and survey were combined in the area of populus,and the collected insect specimens were observed and identified by using microscopes.Result]The results showed that the populus were damaged by three Populus euphratica psyllid which were Egeirotrioza ceardi,Evegeirotrioza gracilis and Homalocephala uncolor.Conclusion]The mixed occurrence of the three Psylla were observed on the same one populus tree,but the damaged time happened at different times. Geirotrioza ceardi had an earlier occurrence than other two insects;the second is Evegeirotrioza gracilis and then Homalocephala uncolor.The result also showed that larva of Homalocephala uncolor occurred earlier than Evegeirotrioza gracilis.
